Methods for determination of plasticizer migration
2 Test methods for plasticizer migration In general, plasticizer migration from PVC synthetic materials can proceed via three different mechanisms, namely volatilization, exudation or extraction, depending on the environment where the PVC coatings are located.
Plasticiser loss from plastic or rubber products through
The formation of the plasticiser film results in a 100 ... E. & Gedde, U. W. Plasticizer migration from PVC cable insulation—the challenges of extrapolation methods. ... M. Migration resistant
Migration of plasticizers from poly(vinyl chloride) and
In addition, we evaluated the migration of plasticizers from PVC raw materials (film and grain) under controlled conditions to compare the migration levels according to Regulation 2011/10. Solid phase extraction and liquid-liquid extraction with gas-chromatography coupled to mass spectrometry were used in all tests.
Performance assessment of polyvinyl chloride films
The migration is decreased as the concentration of ECLO is increased. PVC E film shows no migration in water, designating hydrophobic characteristics of the film, which might be due to the organic nature of ECLO. Previously, the developed plasticizer from the epoxidation of castor oil also exhibited no migration of the plasticizer in water [26
Specification and Evaluation of Plasticizer Migration
Potentially toxic plasticizers are commonly added to polyvinyl chloride medical devices for transfusion in order to improve their flexibility and workability. As the plasticizers are not chemically bonded to the PVC, they can be released into labile blood products (LBPs) during storage. Ideally, LBPs would be used in laboratory studies of plasticizer migration from the medical device. However
- Do plasticizers migrate from MPVC to poly(dimethylsiloxane) via skin?
- There is a potential risk of exposure to PAEs from household PVC articles via skin. In the present study, the migration of plasticizers from modeled and commercial polyvinyl chloride (mPVC and cPVC, respectively) to poly (dimethylsiloxane) via artificial sebum was assessed to mimic the dermal migration of plasticizers.
- How do plasticizers migrate from PVC synthetic materials?
- In general, plasticizer migration from PVC synthetic materials can proceed via three diferent mechanisms, namely volatilization, exudation or extraction, depending on the environment where the PVC coatings are located.
- Why is plasticizer migration important?
- Plasticizer migration is responsible for premature coating failure in polyvinyl chloride (PVC) synthetic materials that continue to benefit our daily life as a reliable and cost-eficient simulant of genuine leather.
- Does plasticizer migration cause premature coating failure?
- Journal of Leather Science and Engineering 4, Article number: 8 (2022) Cite this article Plasticizer migration is responsible for premature coating failure in polyvinyl chloride (PVC) synthetic materials that continue to benefit our daily life as a reliable and cost-efficient simulant of genuine leather.
- Is plasticized polyvinyl chloride harmful?
- However, an application of common plasticized polyvinyl chloride (pPVC) is accompanied by an adverse phenomenon, specifically by the non-negligible and potentially harmful migration of plasticizers into the surrounding media as they are not covalently bound to PVC.
- How do PVC plastics migrate Paes?
- Dermal migration of PAEs from PVC plastics via artificial sebum is assessed. Diffusion and migration are increased with sebum mass and temperature, while decreased with pressure and molar mass of PAE. Diffusion of DINP in soft PVC (cPVC) is higher than hard PVC (mPVC) sample tested.
